Not long after PZ Myers wrote this:
Could it be the start of an avalanche? The Vermont legislature has overridden a governor's veto to sign into a law a bill recognizing gay marriage.
Vermont Becomes Fourth State To Legalize Gay Marriage
I received an e-mail about this:
The D.C. Council has voted to recognize gay marriages performed in other states on the same day that Vermont became the fourth state to legalize same-sex unions.
DC Council Votes to Recognize Other States' Gay Marriages
The Washington Post article goes on to say that the vote was 12-0 on the first ballot.
While I don't see an avalanche, one thing is clear - gay marriage is an acceptable idea in much of America. It's been deemed acceptable by an overwhelming majority of politicians in two places. It won't happen in many places for quite a while, but barring some major change in our national consciousness, it will happen.
